Canon EOS-1Ds Mark III
Hello, anon, and thank you for the question.
This topic has been studied by by researchers for years. There are three prevailing theories that I will relay to you now.
1. It keeps him on the ground.
You may notice in the gif above that Chris’ leg starts to rise as he laughs, possibly a precursor to his entire body undergoing a sort of lift off due to his joy. Chris then employs his upper body strength to force himself to obey the laws of gravity.
2. To check on his physique.
As you may be aware, anon, it takes a lot of hard work to maintain a superhero body. Chris is concerned that in the time he has spent sitting down, sans working out or eating, he has lost muscle mass. Understandably, he feels the need to make sure that he is still a specimen.
3. Object permanence.
Object permanence is a term applied to the understanding that an object still exists even when you cannot see it. Chris closes his eyes when he laughs, making him unable to see that he has not disappeared. By grabbing his left boob, Chris knows that he has not somehow ceased to exist.
I hope this helps.
I will definitely take a look through your tags, and if the videos are not included in there would love a sense of what kind of content they include. please let me know when you post the summary and as soon as michelet and i have worked out some more details we’ll post again here! thanks for offering to contribute.
great, thank you for offering! resource lists are great - i envision this more like a guided discussion than anything else where we curate some key sources along a series of themes so we can spread them throughout tumblr and discuss here. michelet and i are going to work this week on narrowing down the daily themes and then we’ll figure out the best form for submissions.
